We (the labs team) plan to add no more new features / do any non-critical work on OpenStackManager - switch to Horizon is under way :) Other users of OpenStack are also advised to *not* use OSM, if for some reason they think it is a good idea - in fact even we don't have an exact test setup left. So I'm on a closing spree, closing all things directly OSM related. Please re-open with different projects added if you think this would still be an issue on Horizon. Thanks!
